Quick highlights

This custom branch assembly combines a PoweredUSB interface, DB9 connector and RJ12 6P6C interface for a specified POS system. The connector genders, voltage, cable branches and contact assignments follow the actual equipment drawing. A passive cable does not perform USB-to-RS232 protocol conversion unless electronics are explicitly designed and validated.

Overview

Mixed-Interface Cable for Specified POS Equipment

A compact route for systems that combine powered USB access with separate serial or modular equipment connections. It is suited to a verified POS terminal and peripheral combination, with each branch mapped to a known port. Similar connector shapes do not establish compatibility across different host models.

Document Circuit Roles Before Choosing Connectors

Define the PoweredUSB voltage and contact use, DB9 gender and screw hardware, RJ12 gender and 6P6C pin map, branch lengths, labels and molded junction. Goochain can review wiring and mechanical integration for OEM manufacture or ODM development. If protocol conversion is required, specify the active circuit and driver separately.

Provide a Three-Interface Connection Diagram: Send equipment models or port photos, connector mating faces, a circuit map for all three interfaces, branch dimensions and expected quantities. Mark any active electronics as a separate design requirement. Existing 12V product data should stay intact when this content is used to update that product page.

Typical Specs

PoweredUSB interface | Voltage and contact use per system drawing
D-sub interface | DB9, gender and fasteners specified
Modular interface | RJ12 6P6C, gender and wiring specified
Circuit arrangement | Documented power and signal routing
Conversion electronics | Only if explicitly included in the design
Mechanical options | Branch lengths, molded junction and labels

This custom POS cable assembly brings PoweredUSB, DB9 and RJ12 interfaces into one specified branch layout. It is built around the equipment circuit map, not a generic assumption that the connectors exchange protocols.

Document the purpose of each branch

A mixed-interface assembly can combine a power route with a separate equipment signal connection. The drawing should identify which device connects to each end and what each contact carries. A simple block diagram is useful before detailed wire mapping begins.

Separate wiring from protocol conversion

A DB9 connector does not prove that USB is converted to RS232 inside the cable. Some assemblies route an existing serial connection while taking power from another port. If active conversion is required, the circuit, driver and electrical interface must be specified as part of the product.

Develop the branches as one drawing

Goochain provides OEM and ODM engineering support for branch routing, connector selection and sample development in mixed-interface powered USB assemblies. Production takes place at our 5,000 m² Dongguan facility. The PoweredUSB product range also covers simpler connections when the equipment does not need a hybrid harness.

Provide a connection diagram showing the role of each PoweredUSB, DB9 and RJ12 branch. Identify any active conversion circuit separately from the cable wiring.

Custom 5V PoweredUSB Cable Assembly for OEM POS Equipment

Goochain develops 5V PoweredUSB cable assemblies for POS peripherals that cannot be defined by the host plug alone. The device-side connector, pin assignment, power requirement and USB function are reviewed together so the finished cable matches the actual hardware rather than a generic connector description. Power-only and data-enabled versions are treated as different electrical configurations. For OEM and ODM projects, Goochain can develop the cable length, conductor construction, connector overmold, exit direction and strain relief around the equipment layout, then support sample evaluation and controlled production at its 5,000 m² Dongguan factory.
